The decoy effect is a powerful way of manipulating people into making one choice rather than another.

I suspect that a policy of dismissing options that are clearly inferior and writing down a list of only the options you are really considering would help resist the decoy effect. It is worth doing this for many reasons if the choice is important.

And stay away from flight connections that are just 60 minutes, because that makes a significant risk of a missed connection. I would choose option B for those flights, by intentional policy, regardless of C. If I had seen only option A, I would have asked my travel agent, "Can you find a longer connection time?"
